The Tubb's Cafeteria has been closed and is being converted into a new establishment know as "Pick-A-Boo". Whether or not the refillable mug will be offered when the new restaurant opens remains a mystery.
I didn't know the Dolphin had refillable mugs. Do they work like the ones at the WDW Resorts? How much are theirs? We are staying at Boardwalk, but plan to eat over at Tubbi's often (we like the cafeteria style).
The Walt Disney World Dolphin did offer a refillable mug program, unfortunately, the restaurant that was running the show has closed and is being converted into a new establishment (Pick-A-Boo). I will keep you posted on if this new "joint" will offer the mug program when it is due to open in April 2006.
I have the WL thin mugs. In fact, I have one sitting right here on my desk at work. When I was at WL, though, it seemed they offered both this kind and the wider kind. Mine definitely has the slider lid. sip)
The Beach Club and Poly both seemed to only have the wider kind of mugs.
